Aggregated PII

Information that is not PII alone but becomes PII if processed together.

Example:

Blood type, last name and postal city taken individually alone do not identify an individual. O+

Harris

Edinburgh

However, when combined, these data points can be used to identify a specific individual.

Example:

Blood type, last name and postal city together may identify an individual.

A person with the last name Harris, with O+ blood of Edinburgh.
